我国带电作业的发展简史（1953~2009）

Brief history of the development of live working in China (1953-2009)

我国的带电作业技术起步于20世纪50年代，当时正处于国民经济恢复和发展的初期。由于发电量迅速增长，电力设备明显不足，大工业用户对连续供电的需求日益严格，常规的停电检修因而收到限制。当时，我国大的钢铁基地鞍山，扁电缆YCB3*11+2*9卷筒扁电缆停电尤为困难。为了解决线路要检修而用户又不能停电的矛盾，当时称之为“不停电检修技术”开始得到发展与应用。

China's live working technology started in the 1950s, when it was in the early stage of national economic recovery and development. Due to the rapid growth of power generation and the obvious shortage of power equipment, the demand of large industrial users for continuous power supply is increasingly strict, so the routine outage maintenance is limited. At that time, Anshan, China's largest steel base, was particularly difficult to cut off power. In order to solve the contradiction that the line needs to be overhauled and the user can't cut off the power, the so-called "on line maintenance technology" began to be developed and applied.

1953年，鞍山电业局的工人开始研究带电清扫、更换和拆装配电设备及引线的简单工具。

In 1953, workers in Anshan Electric Power Bureau began to study simple tools for cleaning, replacing and disassembling power distribution equipment and leads with electricity.

1954年，采用类似桦木的木棒来制作的工具完成了3.3KV配电线路不停电更换横担、木杆和瓷瓶的作业。尽管工具显得十分笨重粗糙，但却成功地进行了3.3KV配电线路的“地电位”带电作业，也是第一次实现带电作业。

In 1954, a birch like tool was used to replace crossarms, wooden poles and porcelain bottles for 3.3kV distribution lines without power failure. Although the tools are very bulky and rough, the "ground potential" live working of 3.3kV distribution line ha
